Vector3 Struct

Representation of 3D vectors and points.

This structure is used throughout Unity to pass 3D positions and directions around. It also contains functions for doing common vector operations.

Besides the functions listed below, other classes can be used to manipulate vectors and points as well. For example the Quaternion and the Matrix4x4 classes are useful for rotating or transforming vectors and points.

Variables
x

X component of the vector.

y

Y component of the vector.

z

Z component of the vector.

this [int index]

Access the x, y, z components using [0], [1], [2] respectively.

normalized

Returns this vector with a magnitude of 1 (Read Only).

magnitude

Returns the length of this vector (Read Only).

sqrMagnitude

Returns the squared length of this vector (Read Only).

Constructors
Vector3

Creates a new vector with given x, y, z components.

Functions
Scale

Multiplies every component of this vector by the same component of scale.

Normalize

Makes this vector have a magnitude of 1.

ToString

Returns a nicely formatted string for this vector.

Class Variables
zero

Shorthand for writing Vector3(0, 0, 0)

one

Shorthand for writing Vector3(1, 1, 1)

forward

Shorthand for writing Vector3(0, 0, 1)

up

Scale

Multiplies two vectors component-wise.

Cross

Cross Product of two vectors.

Reflect

Reflects the vector along the normal.

Dot

Dot Product of two vectors.

Project

Projects a vector onto another vector.

Angle

Returns the angle in degrees between from and to.

Distance

Returns the distance between a and b.

Min

Returns a vector that is made from the smallest components of lhs and rhs.

Max

Returns a vector that is made from the largest components of lhs and rhs.

operator +

Adds two vectors.

operator -

Subtracts one vector from another.

operator *

Multiplies a vector by a number.

operator /

Divides a vector by a number.

operator ==

Returns true if the vectors are equal.

operator !=

Returns true if vectors different.
